1, the toner (mechanism 1) supplied by advancing wave
(the toner supplying structure of developer replenishing mechanism)
Next, the toner supplying structure of developer replenishing mechanism 200 is schematically described with reference to Fig. 1 to Fig. 3.At this, developer replenishing mechanism 200 comprises and holds container 14, supply member 10b and can vibration component 13.
In figure 3, component (a) is the schematic diagram of developer replenishing mechanism 200, and component (b) is the oscillogram of advancing wave.As shown in Figure 3, the accommodation container 14 for holding powder (being developer in this embodiment) is comprised as the developer replenishing mechanism 200 of powder feeding mechanism.Hold container 14 and comprise container body 14a and container cover component 14b.When container cover component 14b is installed to container body 14a, define opening 19.In addition, when box B is arranged in equipment primary clustering A, the backplate surface 14x of container body 14a is configured to basic horizontal.Incidentally, opening 19 is such openings, and the toner held in container 14 is supplied (Fig. 2) to developer roll 10d for allowing by this opening.
Next, supply member 10b will be described.Supply member 10b is arranged in below powder, and is tabular component, for supplying developer.Supply member 10b is arranged on the backplate surface 14x of accommodation container 14.Supply member 10b is constructed such that being fixed at least partially of supply member 10b can vibration component 13, and produce in supply member 10b by as (generation) source can the advancing wave (advancing wave generating step) that produces of vibration component 13 and supply member 10b supplies developer (powder feeding step) along the direction of the supply J1 as powder feeding direction.This direction of the supply J1 can also be expressed as the working direction of advancing wave.
Incidentally, developer replenishing mechanism 200 is different from holding the direct structure vibrated or swing of container 14 and developer replenishing mechanism 200 is such structures, and in described structure, the supply member 10b be placed on the backplate surface 14x holding container 14 vibrates.This is because when holding container 14 and vibrating or swing, be provided for and hold container 14 and to vibrate or the mechanism that swings needs to be arranged on outside accommodation container 14, and need to guarantee the space needed for this mechanism, therefore described mechanism and space useless, therefore adopt the structure that embodiment above describes.In addition, adopt above-mentioned structure also in order to avoid such situation, that is, when holding container 14 and directly vibrating or swing, produce the error etc. about the positional precision of developer roll 10d fitted together with accommodation container 14 and negative influence can be produced to imaging.
About supply member 10b, its free end about direction of the supply J1 is free end part 10b2, and its bottom about direction of the supply J1 is fixed part 10b1.Fixed part 10b1 is fixed to can vibration component 13, for transferring vibrations to supply member 10b and forming anchor portion.Free end part 10b2 is not fixed to backplate surface 14x and forms free end.
In addition, as the material for supply member 10b, use the silicone rubber that 300 μm thick, but material can also be not limited to this silicone rubber material.Material for supply member 10b can also be general elastomeric material, such as acrylic rubber, natural rubber or butyl rubber.Material for supply member 10b can also be general-purpose plastics material, such as polyethylene terephthalate (PET), polystyrene (PS), tygon (PE), polypropylene (PP), ABS resin, polycarbonate (PC) or polyacetal (POM).
Next, can vibration component 13 by description.Reciprocating acceleration can be applied to supply member 10b, to vibrate along the vertical direction perpendicular to the developer replenishing surface as powder feeding surface by vibration component 13.The upstream end of supply member 10b can be arranged in by vibration component 13 relative to direction of the supply J1.
When can vibration component 13 along vertical direction F1 vibration perpendicular to supply member 10b time, the vibration of vibration component 13 can be delivered to supply member 10b via direction of the supply 10b1, supply member 10b be divided in 10a at toner accommodating part and vibrates.At this, select the vibration frequency of 40Hz and the amplitude of about 0.8mm.Can be arranged near the rear end part 14c relative with the opening 19 holding container 14 by vibration component 13, and be formed with the surface portion 13a of inclination in part thereon.
In addition, can be made up of a component by vibration component 13, described component is by can vibrative general vibration bringing device body or vibration bringing device (such as, piezoelectric element) and vibrate.
At this, as shown in Figure 3, when can vibration component 13 vibrate time, the fixed part 10b1 of supply member 10b, along the vertical direction F1 to-and-fro movement perpendicular to supply member 10b, makes vibration transmit to the free end part 10b2 of supply member 10b from fixed part 10b1.At this moment, in the direction of the supply 10b1 side of supply member 10b by being greater than the peak swing A2 in the free end part 10b2 side of supply member 10b by the peak swing A1 that produces of vibration component 13.
The amplitude of the vibration being applied to supply member 10b this is because the absorption of vibrations self caused by supply member 10b has decayed.As a result, produce advancing wave, in described advancing wave, peak to the valley of supply member 10b is divided from fixed part 10b1 side direction free end part 10b2 lateral movement.
At this, be positioned in the toner of the surface element office of the inclination of advancing wave and there is such toner (component), the surface that described toner can not remain in inclination drops in the wave trough portion of advancing wave.Now, wave trough portion moves together with advancing wave, and therefore by repeating this operation, can supply toner along the direction identical with advance wave line of propagation.
Therefore, by making advancing wave move from fixed part 10b1 to free end part 10b2, feed the toner on supply member 10b along direction (direction of the supply) J1 pointing to opening 19 side holding container 14.
At this, in the high frequency situations of the vibration period of such as 50kHz, as described in Jap.P. No.2829938, it is well known that toner moves along the direction contrary with advance wave line of propagation.But, as in this embodiment, in low frequency region, will consider not apply this feed mechanism, but toner according to said mechanism along advance wave line of propagation.
In addition, the surface portion 13a of inclination is arranged on can the upper part place of vibration component 13, therefore, can toner on vibration component 13 can because can the vibration of vibration component 13 slide, to arrive at supply member 10b on the surface portion 13a tilted.For this reason, the surface portion 13a of inclination prevent toner from remaining in can on vibration component 13.

As the material for supply member 10b, use the polystyrene (PS) that 1mm is thick, but this material is not limited to polystyrene material.Material for supply member 10b by general-purpose plastics material (such as polyethylene terephthalate (PET), polystyrene (PS), tygon (PE), polypropylene (PP), ABS resin, polycarbonate (PC) or polyacetal (POM)) or suitably can also be made up of general purpose resilient body material (such as, silicone rubber, acrylic rubber, natural rubber or butyl rubber).
As shown in Figure 4, on supply surface direction F2, to-and-fro movement acceleration can be applied to supply member 10b, to vibrate along developer replenishing surface by vibration component (vibration applies component) 13.When can vibration component 13 vibrate time, can the vibration of vibration component (vibration apply component) 13 via the fixed part 10b1 of vibration component (vibration bringing device) 13 and supply member supply member 10b can be delivered to, supply member 10b is divided in 10a at toner accommodating part and vibrates.
Now, by making to vibrate by vibration component 13, the free end part 10b2 of supply member 10b moves to position 10b21 and position 10b22, at 10b21 place, described position, free end part 10b2 moves to greatest extent along direction of the supply J1, at 10b22 place, described position, free end part moves to greatest extent along the reverse direction J2 contrary with direction of the supply J1.
At this, selecting can the vibration frequency of 50Hz of vibration component 13 and the movement length L of about 0.6mm, and described movement length is the difference between the position 10b21 of the free end part 10b2 of supply member 10b and position 10b22.
As shown in Figure 4, supply member 10b is provided with free end part 10b2 as free end in opening 19 side holding container 14, and in the sidepiece contrary with free end part 10b2, be provided with that be fixed to can the fixed part 10b1 of vibration component (vibrate and apply component) 13.
At this, when can vibration component (vibration apply component) 13 vibrate along the supply surface direction F2 that the thickness direction with supply member 10b intersects time, the fixed part 10b1 of supply member 10b vibrates, and the fixed part 10b1 vibrated from supply member 10b is transmitted to free end part 10b2.At this moment, by can the vibration of vibration component (vibration apply component) 13, by the peak acceleration a1 along direction of the supply J1 be applied to supply member 10b along the peak acceleration a2 of the reverse direction J2 contrary with direction of the supply J1.

In addition, as the material for supply member 10b, use the silicone rubber that 0.3mm is thick, but material is not limited to silicone rubber.Material for supply member 10b suitably can also be made up of general purpose resilient body material (such as, acrylic rubber, natural rubber or butyl rubber).
As shown in Figure 5, toner accommodating part divides the supply member 10b in 10a to be fixed at fixed part 10b1 place and holds container 14.By this way, only require supply member 10b to be fixed at least one position.
As shown in Figure 5, periodically implement such operation, in described operation, power F3 pulls the free end part 10b2 of supply member 10b along direction of the supply J1, then cancels this and pulls.
In this embodiment, supply member 10b is provided with contact portion 16, accelerates to-and-fro movement for the supply surface direction F2 making supply member 10b intersect along the thickness direction with supply member 10b in accommodation container 14.In addition, in accommodation container 14, as can the rotatable cam component 15 of vibration component (vibration apply component) be arranged to relative with the contact portion 16 be arranged on supply member 10b.
To-and-fro movement acceleration is applied to supply member 10b along developer replenishing surface via contact portion 16 by cam member 15 on supply surface direction F2, to make supply member 10b expand and to shrink.As a result, be applied with and be provided for supply member 10b along supply surface direction reciprocating vibration.
Such situation is exemplarily described, in the described situation, the reciprocating contact portion 16 of supply surface direction F2 can intersected along the thickness direction with supply member 10b is moved holding in container 14 by cam member 15, but contact portion 16 can also by the vibration bringing device of such as piezoelectric element (vibration applies component) motion.
As a result, the supply member 10b repetitive extension be made up of the silicone rubber as high resiliency component and contraction, thus divide the supply surface direction F2 intersected along the thickness direction with supply member 10b in 10a to vibrate at toner accommodating part.
Now, by making to vibrate by vibration component 13, the free end part 10b2 of supply member 10b moves to free end part 10b2 and moves to position 10b21 to greatest extent along direction of the supply J1, and moves to free end part and move to position 10b22 to greatest extent to J2 on the contrary along contrary with direction of the supply J1.
At this, selecting vibration frequency to be applied to the power F3 of the free end part 10b2 of supply member 10b and the movement length L of about 0.6mm, the described movement length L of 50Hz is difference between the position 10b21 of the free end part 10b2 of supply member 10b and position b22.In addition, the elastic force of about 200gf/mm and the toner weight of about 100g of supply member 10b is selected.
Supply member 10b vibrates because the cycle implements such operation, and in described operation, power F2 pulls the free end part 10b2 of supply member 10b along direction of the supply J1, pulls described in then cancelling.By this vibration, by the peak acceleration a1 along direction of the supply J1 be applied to supply member 10b along the peak acceleration a2 of the reverse direction J2 contrary with direction of the supply J1.
At this, by the revolution adjusting cam member 15, the peak acceleration a1 being applied to supply member 10b along direction of the supply J1 by cam member 15 is arranged to be less than the peak acceleration a2 (acceleration setting procedure) being applied to supply member 10b by cam member 15 along the reverse direction J2 contrary with direction of the supply J1.By this acceleration setting procedure, supply developer (powder feeding step) by supply member 10b along direction of the supply J1.
At this, by setting acceleration, the peak acceleration a1 along the direction of the supply J1 of supply member 10b is made to be less than the peak acceleration a2 of J2 in the opposite direction, compared with along between direction of the supply J1 moving period, between J2 in the opposite direction moving period, the sliding distance of toner on supply member 10b is longer.In addition, when supply member 10b moves along the reverse direction J2 contrary with direction of the supply J1, the toner that supply member 10b slides moves along direction of the supply J1 relative to fixed part 10b1 on supply member 10b.As a result, by repeating above-mentioned vibration, the toner on supply member 10b is fed gradually along direction of the supply J1.
On the other hand, at supply member 10b to move along the reverse direction J2 peak acceleration a2 contrary with direction of the supply J1, toner is when sliding on supply member 10b with this peak acceleration a2, developer is not supplied to.That is, in the present invention, when supply member 10b moves along the reverse direction J2 contrary with direction of the supply J1, require that supply member 10b has maximum acceleration, toner can be slided on supply member 10b.
Now, toner vibration supply member 10b on slip be not limited between supply member 10b and toner, between supply member 10b and toner interface place produce slip, but toner (component) can also be included in and be positioned between the upper toner (component) on toner interface place generation slip.In addition, vibration applies component 13 and is not limited to above-mentioned structure, but can also be structure as shown in Figure 5, makes, by rotating cam member 15, vibration is applied to the contact portion 16 be arranged on supply member 10b.
Fig. 6 comprises the schematic diagram of developer replenishing mechanism, and in described developer replenishing mechanism, supply member 10b is connected with elastic component 17.In figure 6, component (a) is the sectional view of developer replenishing mechanism, and component (b) is the partial enlarged drawing of the component (a) of Fig. 6, and component (c) is the skeleton view of developer replenishing mechanism.Incidentally, in this modified example, supply member 10b can be limited and elastic component 17 forms supply member.
Supply member 10b is formed by general plastic material.Elastic component 17 is formed by general purpose resilient body material.In addition, elastic component 17 is connected with the fixed part 10b1 of supply member 10b in left side, and is connected with the rear end part 14b holding container 14 on right side.
At this, illustrate such situation, in the described situation, supply member 10b is moved by cam member 15, but supply member 10b can also move because of the vibration bringing device of such as piezoelectric element.

4, by changing toner supply (mechanism 2) of the wavelength of standing wave
At this, the toner supplying structure of developer replenishing mechanism is not limited to above-mentioned structure.Such as, toner supplying structure can also be the toner supplying structure be made up of the developer replenishing mechanism 400 shown in Fig. 7.In the figure 7, component (a) is the sectional view of the developer replenishing mechanism 400 according to embodiment 4, and component (b) is the oscillogram of standing wave.Fig. 8 shows the schematic diagram of the motion state of oscillogram and developer.Those composed components identical with those composed components in embodiment 1 to 3 in embodiment 4 are represented and will the descriptions thereof are omitted with identical Reference numeral or mark.Description in each in embodiment 1 to 3 can also be applied to this embodiment.
(the toner supplying structure of developer replenishing mechanism)
The toner supplying structure of the developer replenishing mechanism 300 in this embodiment is specifically described with reference to Fig. 1,2,7 and 8.At this, developer replenishing mechanism 400 comprises and holds container 14, supply member 10b and can vibration component 13.
In addition, as the material for supply member 10b, use the silicone rubber that 300 μm thick, but material is not limited to silicone rubber.
Material for supply member 10b can also be suitably made up of general purpose resilient body material (such as, acrylic rubber, natural rubber or butyl rubber).Material for supply member 10b can also be general-purpose plastics material, such as polyethylene terephthalate (PET), polystyrene (PS), tygon (PE), polypropylene (PP), ABS resin, polycarbonate (PC) or polyacetal (POM)).
As shown in Figure 7, toner accommodating part divides the supply member 10b of 10a and can be connected by vibration component 13, described can vibration component for transferring vibrations to the fixed part 10b1 place of supply member 10b, and described supply member 10b is fixed to container body 14a at the fixed part 10b3 of free end part 10b2 side.
As shown in Figure 7, vibration component 13 to-and-fro movement acceleration can be applied to supply member 10b along the vertical direction F1 perpendicular to developer replenishing surface, to vibrate.By producing standing wave (standing wave generating step) by vibration component 13 as (generation) source in supply member 10b.Then, standing wave frequency (frequency increase step) is increased.As a result, supply member 10b supplies developer (powder feeding method) along direction of the supply J1.Can the frequency of vibration component 13 can be the type that the type that increases continuously of frequency or frequency become stepped increase.But, first, by the situation that description frequency increases continuously.
By the vibration that produces of vibration component 13 supply member 10b can be delivered to via direction of the supply 10b1, supply member 10b be divided in 10a at toner accommodating part and vibrates.At this, select the amplitude of the vibration frequency between 40Hz to 120Hz and about 0.8mm.
At this, as shown in Figure 7 and Figure 8, when can vibration component 13 vibrate with 40Hz time, the fixed part 10b1 of supply member 10b, along the vertical direction F1 to-and-fro movement perpendicular to supply member 10b, makes vibration transmit to free end part 10b2 from the fixed part 10b1 of supply member 10b.Now, fixed part 10b3 secure free end portion part 10b2, makes vibrative reflection wave.As a result, in supply member 10b, form the standing wave be made up of the composite wave of advancing wave and reflection wave.
At this, as shown in Figure 8, the toner on supply member 10b is gathered in such region (node), in described region (node), produces the standing wave slight vibration on supply member 10b.From this state, when frequency increases continuously gradually to 120Hz, the wavelength of standing wave shortens gradually.The shortening of the wavelength of standing wave means to move to free end part 10b2 from fixed part 10b1 according to the contraction of wavelength in the region (node) of standing wave slight vibration.Therefore, the toner be gathered in the described region (node) of standing wave slight vibration also moves.
By this way, when frequency increases continuously, only require that frequency increases, make the toner being gathered in Nodes along with moving along direction of the supply J1 and move along direction of the supply J1 in the region (node) of standing wave slight vibration.
At this, frequency does not increase continuously, but can increase with the order step-by-step movement of 40Hz, 60Hz, 80Hz, 100Hz and 120Hz with the recruitment of 20Hz.By this way, when frequency progressively increases, only require that frequency is increased to the frequency of next grade experience the schedule time the region (node) moving to standing wave slight vibration from toner after.
Then, the frequency increase reaching 120Hz once stopping and frequency retrieval to 40Hz, and then to increase.Especially, preferably when considering powder feeding, frequency is increased to 120Hz continuously or steppingly and is after this decreased to 40Hz suddenly, and then is increased to 120Hz.By repeating increase and the reduction of this frequency, more effectively powder can be supplied.In addition, the toner moving to node when frequency is 120Hz along direction of the supply J1 move to relative to the supplying party anti-node position that J2 locates in the opposite direction before, frequency is decreased to 40Hz continuously or steppingly from 120Hz, and then increases.
By repeating this operation, toner can be supplied from fixed part 10b1 to free end part 10b2.
Namely, this is because the toner moving to the node of 120Hz is positioned at the downstream part of region (antinodal points) relative to direction of the supply J1, at this place, the antinodal points of the standing wave formed under the condition of frequency 40Hz becomes maximum, therefore, relative to direction of the supply J1 by toner supply to downstream node.
Now, can only require can the maximal value of frequency of vibration component 13 be set greater than can the twice of minimum value of frequency of vibration component 13.This is because as shown in Figure 8, as the node locating of the frequency of the 80Hz of the twice of the frequency of 40Hz at the antinodal points place of 40Hz, therefore at least half toner moves to downstream node place relative to direction of the supply J1.
At this, usually, when developer is on oscillating plate, it is well known that, the developer in the region (antinodal points) that the standing wave that flips vibrates largely, and developer is gathered in the region (node) of standing wave slight vibration.In this embodiment, standing wave is formed on supply member 10b, and increases continuously in wave frequency, makes the region (node) of standing wave slight vibration move thus.As a result, the toner supply member 10b is fed from fixed part 10b1 towards free end part 10b2.
In addition, inclined surface part 13a is arranged on can the upper part place of vibration component 13, and therefore can toner on vibration component 13 can because of can vibration component 13 vibration and slide on inclined surface part 13a, to arrive at supply member 10b.For this reason, inclined surface part 13a prevent toner from remaining in can on vibration component 13.
